Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned or cooked tomatoes
- Provide the main body, moisture and acidity of the sauce.
- Onion
- Softened in the pan, it adds sweetness and savoury depth to the base.
- Garlic
- Frying releases its aroma, which flavours the whole sauce.
The step that matters
Reducing the sauce by about one-third. Boiling drives off water and concentrates the flavour while thickening the sauce. Reducing too little leaves it thin and watery, while reducing too far can make it overly intense and pasty.
Swap the clove
How well each one fits the dish's main ingredients (tomato, garlic, onion, parsley, thyme):
- Oreganofits better
- Marjoramfits better
- Cuminfits better
- Clovethe original
Fit is the average pairing score against tomato, garlic, onion, parsley, thyme. Candidates are from the same food group and used in at least 100 recipes.
